  2. 1. Structure, function and metabolic stability of antisense RNAs

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fredrik Söderbom; Uppsala universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Antisense RNAs usually are small, highly structured, unstable RNAs that control a varietyof different biological processes. They exert their effect by binding to complementarytarget RNAs and thereby inhibit their functions. READ MORE

    Abstract : The study of bacterial evolution is fundamental for addressing current problems of antibiotic resistance and emerging infectious diseases and lays a solid foundation for successful and rational design in biotechnology and synthetic biology. The main aim of this thesis is to test evolutionary hypotheses, largely based on theoretical considerations and sequence analysis, by designing scenarios in a laboratory setting to obtain experimental data.

  5. 3. Host-Pathogen Responses during Giardia infections

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Emma Ringqvist; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Giardia; parasite infection; host-parasite releationship; immune activation; virulence factor; immune evasion; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Giardia lamblia is a eukaryotic parasite of the upper small intestine of humans and animals. The infecting trophozoite cells do not invade the epithelium lining of the intestine, but attach to the brush border surface in the intestinal lumen. The giardiasis disease in humans is highly variable. READ MORE

  6. 4. The type I-E CRISPR-Cas system Biology and applications of an adaptive immune system in bacteria

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lina Amlinger; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CRISPR; CRISPR-Cas; virus defense; bacteria; bacteriophage; adaptation; spacer integration; interference; gene silencing; fluorescent reporter; Escherichia coli; Mikrobiologi; Microbiology;

    Abstract : CRISPR-Cas systems are adaptive immune systems in bacteria and archaea, consisting of a clustered regularly interspaced short palindromic repeats (CRISPR) array and CRISPR associated (Cas) proteins. In this work, the type I-E CRISPR-Cas system of Escherichia coli was studied.CRISPR-Cas immunity is divided into three stages. READ MORE

  7. 5. EF-Tu and RNase E Essential and Functionally Connected Proteins

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Disa L. Hammarlöf; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial growth; translation; EF-Tu; RNase E; mRNA; RNA degradation; Molekylär cellbiologi; Molecular Cellbiology; Mikrobiologi; Microbiology;

    Abstract : The rate and accuracy of protein production is the main determinant of bacterial growth. Elongation Factor Tu (EF-Tu) provides the ribosome with aminoacylated tRNAs, and is central for its activity. In Salmonella enterica serovar Typhimurium, EF-Tu is encoded by the genes tufA and tufB.
